    Ditto.  Same problem.  But didn't start right away.  I've been running Lion for about a week, but it just started today.  ANNOYING!

    Was having wi-fi drop issue with my late 2009 iMac.  Full wi-fi bars all the time, but connection would drop all the time.  tried all the suggestions in this thread to no avail.


    updated to 10.7.1, deleted preferred networks, then added my home network back on.  Was online for 12+ hours and thought 10.7.1 fixed the problem.  Now it has just dropped again.  Same behavior:  full wifi bars, but no connectivity.  So frustrating!  Never had any issues under Snow Leopard.

    As a lifetime Windows user and a frequent (recently, more frequently with all the new Apple hardware I now own) Mac user, I started thinking to myself how Lion could be Apple's "Vista".  I stumbled upon an article by someone with the same conclusion.


    I think Apple needs to figure out some of these problems and get Lion working correctly, lest we all will be waiting for 10.8!

    When your connection drops (and you still have full WiFi bars), can you try to ping a dns address like, www.google.com? If you can ping that address, but other apps like Safari, mail etc cannot get out, then you do not have a wireless issue rather a stack issue.


    If you find you have a stack issue, I would call AppleCare post haste and tell them about this experiment.


    Let us know.

    OK... good tip.  I will try the next time it happens.  Thank you.

    If you are having a hard time getting DHCP to renew, just eliminate the problem by making a manual IP assignment to the IP that you get via DHCP.  Then there is no renewal at all.  See if that fixes your issue.

    I've since downgraded to 10.6.8. AGAIN. I'm going to wait til at least 10.7.3 or hopefully some sort of "Wi-Fi Patch Kit" to come out. If the problem still occurs I'm going to just keep 10.6.8 and partition off another part of my drive to run Debian or Yellow Dog. Cause at this point I'm really sick of what Apple is pretending isn't a "big deal." They run you through all kinds of so-called "fixes" that the guy on the other line KNOWS DON'T WORK, but because of "tiered support" they have to do. As it stands now Apple is about to lose a customer of 25 years. Once this iMac is outddated (another 6 months) I'm taking my hardware requirements elsewhere.


    I'm very disappointed, Apple. Very.

    Nicely put, Abraham.


    I think frustration with Lion is running really high. People are starting to call this Apple's Vista. Yikes!


    Topher Kessler states: "The updater package does not contain any Wi-Fi related updates, so it is unexpected that this behavior should change." If this is true, why in the world did Apple say .1 would fix the problem?"


    Since Apple put the upgrade through the App Store in Snow Leopard, I think they should have a quick and easy downgrade to 10.6.8 available. People could stay with that until discussion boards indicate that all is clear with Lion. I don't think it will work well until 10.7.3, since the .2 upgrade is going to have so many new features designed to work with new cloud technology. Bound to be a lot more problems to sort through. Anyway, a little "downgrade to Snow Leopard" could download 10.6.8, and a "Reinstall Lion" could download and install latest Lion.


    Of course, that would be an admission that something is really wrong under the hood with Lion!

    I wish I could downgrade back to 10.6.8, but I don't know too much about computers thats why i bought the Mac because of its use-ability which with mac os x lion is almost impossible!! This wifi dropping makes me so paranoid while shopping online, thinking my connection is going to drop. Worst part is it always shows full bars so i'll never know if it drops while reading a web site. Apple used to fix these problems quickly, but lately they have been dropping the ball big time! I know a fix is far off. I'm switching to my crappy windows 7 netbook that has reliable wifi (a basic thing!) until one day maybe apple fixes this disaster

    I have installed 10.7.1 and I am still having wifi issues. The update did not fix it.
